Python program to calculate sum of prime numbers between 1 to n

In this article, we will discuss the concept of Python program to calculate sum of prime numbers between 1 to n

In this code, we are going to learn how to find sum of prime numbers 1 to n using different methods in Python language.

This is done using for loop, in Python language

Code to display sum of prime numbers

Code to calculate sum of prime numbers using for loop

In this program, we will calculate sum of prime numbers 1 to n using for loop in Python language

Program 1

#takes input from the user
max=int(input("Enter the maximum value for find sum of primes:"))
sum=0
for num in range(2,max+1):
    i=2
    for i in range(2,num):
        if(int(num%i==0)):
            i=num
            break;
        #when the number is prime calculate sum
    if i is not num:
        sum+=num
print("Sum of all prime numbers 1 to ",max,":",sum)

When the above code is executed, it produces the following result

Enter the maximum value for find sum of primes:100
Sum of all prime numbers 1 to  100 :1058

Code to calculate sum of prime numbers between 1 to n -method 2

Program 2

#Python program to find sum of prime numbers from 1 to n
maximum=int(input("Please enter the maximum value: "))
total=0
for Number in range(1,maximum+1):
    count=0;
    for i in range(2,(Number//2+1)):
        if(Number%i==0):
          count=count+1
          break
    if(count==0 and Number !=1):
        
        total=total+Number
print("Sum of prime numbers from 1 to %d=%d"%(maximum,total))

When the above code is executed, it produces the following result

Please enter the maximum value: 50
Sum of prime numbers from 1 to 50=328

Code to calculate sum of prime numbers between 1 to n -method 3

Program 3

#Python program to find sum of prime numbers from 1 to n
maximum=int(input("Please enter the maximum value: "))
total=0
for Number in range(1,maximum+1):
    count=0;
    for i in range(2,(Number//2+1)):
        if(Number%i==0):
          count=count+1
          break
    if(count==0 and Number !=1):
       # print("%d"%Number)
        total=total+Number
print("Sum of prime numbers from 1 to %d=%d"%(maximum,total))

When the above code is executed, it produces the following result

Please enter the maximum value: 100
